I have a model with about 750 objects. On my M2 MacBook Air, merely selecting a folder in the object tree can take ten seconds. Performance seems to degrade linearly as a model file is populated with objects as modelling progresses, indicating that selecting a folder is somehow enumerating all the objects in a model when a folder might only contain a tiny fraction of those objects.

Please can you try and optimise-further folder selection?
